摘要： PROBLEM TO BE SOLVED: To detect the rotary angle of a spherical body accurately by a compact and simple configuration by arranging an electrode plate for constituting a capacitance in a space that is formed at an area to an electrode part while the capacitance opposes the electrode part provided on the surface of the spherical body. SOLUTION: A spherical body 10 that is supported so that it can rotate freely is formed nearly spherically of insulation material such as ceramic and a shaft part 11 is connected to an upper surface. A nearly square electrode film 12 is applied to the lower surface of the spherical body 10 and electrode plates 13-16 that are divided into four portions are arranged at the lower part of the electrode film 12. The electrode plates 13-16 form a concentric spherical shape with the spherical part of the spherical body 10 and the gap between the electrode plates 13-16, and the spherical body 10 is constant, thus a capacitance is constituted between the electrode film 12 and the electrode plates 13-16. A capacitance detection circuit detects the capacitance between the electrode film 12 and the electrode plates 13-16, and each output CA, CB, CC, CD, and G are supplied to an operation circuit, thus the rotary angle of the spherical body 10 is calculated.
